Hello all! I am new to the forum, and new to guinea pigs. After about a month of prep work, to make sure they woule be the right addition to our family, we went out and picked some up. Unfortunately, we had to pick them up from a pet store. (I didnt want to drag my family on a six hour trip to our nearest rescue.) We got two, each from a different location. The first place was very knowledgable. They knew the age and where they came from. However, the second place I went said the pig I got was anywhere from 3 to 8 months old. She is just barely the size of my hand though. When struggling, she can squeeze through the grid spaces. (It takes alot of work though) Any guesses on how old she might be, based on the size of a grid space?
